Cover Star Structures is a leading manufacture of modular dome shelters in B.C. With a need to separate the welding area from the curtain finishing area a strip door curtain was installed on a 13′ W X 14′ H opening to reduce dust and particle transfer. Strips supplied were of 12″ width with ribs. The overlap was a common 4″ or 67% overlap. Not only will the door prevent dust and particle transfer between two rooms but will also reduce noise , and contain heat.
